In every home, office, church, school or college, repairing a roof will inevitably become a necessary evil you can no longer ignore. Moisture needs to be kept away and the structure of any building needs to be protected from rot. Roofs that have been well built will provide endless years of good service and no damage should incur unless there has been a storm or a bad winter with hail. But wear and tear is inevitable at some stage in any roof, regardless of how well it has been constructed.
First you need to decide if your roof is damaged to the point where you will need to replace the whole thing or is it damaged only in certain places and can it be repaired? A well constructed roof should last around 25 years but if you spot loose shingles, tiles that have become cracked and worked loose on the nubs or excessive moss forming on the tiles then you’ll know it is in need for some tender loving care and attention.
The option to select a whole new roof is always tempting and the “rip it off and start again” procedure does sound nice, like a clean sweep and whole new roof is there from scratch. But what if your roof has a majority of its area that is still sound and the damage is limited to just a few isolated areas that are in need of repair? You would not dream of buying a whole new car just because the windscreen is cracked, so why would you get a complete new roof, at great expense, when a few minor repairs can get your roof looking as good as new again, and at a fraction of the cost of a full replacement?
However, there is another option where you could consider going somewhere between the two choices of repair and replace; a new roof layer could be a good option if your roof still has plenty of strength and mileage ahead of it. A new roof layer is a good option for roofs that have just the one layer and in reasonably good condition anyway.
The procedure would involve all the tiles being removed before a new, tight and well-sealed layer is applied. The next stage is to carefully replace the existing tiles back on the roof as before.
